Building Permit Amendment

An amendment is required for any change made to an existing scope of work or design element(s) of an issued permit. Additionally, amendments are required to update or add Mechanic Lien Agent (MLA) contact information on an issued permit.

This information is the most common for how to obtain the necessary approval for your project and is not representative of all the conditions you may encounter.



Only the contacts listed on the original permit record may apply for an amendment in PLUS.



Before submitting, ensure you are aware of all applicable regulations and conditions that could affect your project to avoid surprises during the review process. Some of those factors include:

  • Zoning Information
  • Design Codes and Standards
  • Do I need to hire a Registered Design Professional (RDP)?
  • Floodplains
  • Resource Protection Areas (RPA)
  • Grading/Site plans
  • Parking Tabulation
  • Types of Soils and Problem Soils
  • Researching Site Conditions


To get a detailed description about each regulation and condition, visit our Plan Ahead page.

What's Next?

Once the amendment is submitted, the original permit record status will update to “Issued – Amendment Pending.” The Building Permit Amendment will use the original Building Permit record number, followed by the number of the amendment (e.g., 01, 02, 03).

County Review

Staff from the Permit Application Center will review your submission for completeness and compliance with the building code and county ordinances. If plans are required, your application will be routed to the appropriate review staff. You will be notified of any deficiencies. Corrections, resubmission fees and additional supporting documents may be required.

Permit amendment fees are paid prior to issuance of the amendment.


 Permit Issuance

Once all county reviews are approved and fees paid, the amendment record will update to “Closed.” The status of the original permit record which was amended will update back to “Issued.” A revised permit card and approved plans, if applicable, will be available to download from PLUS, under your original permit.

Inspections cannot be scheduled while there is an active amendment in process. Once the amendment is approved and in the “closed” status, and the original permit record returns to a status of “issued” and not “issued - amendment pending,” inspections can be scheduled.

The county must be notified once stages of construction are reached that require an inspection. For more information, see our inspections webpage.
